ToupTek ATR432C Deep Sky Cooled Camera – Sony IMX432 Colour

The ToupTek ATR432C is a professional colour (one-shot colour) deep sky cooled camera built around the Sony IMX432 global shutter sensor with a Bayer colour filter array. It delivers excellent colour deep sky imaging performance combined with the convenience of a single-shot colour workflow — ideal for astrophotographers who want stunning results without the complexity of separate LRGB filter sets.

Who Is This Product Best For?

The ATR432C is best for intermediate to advanced astrophotographers who prefer one-shot colour (OSC) imaging of nebulae, galaxies, and star clusters. Its global shutter also makes it suitable for lucky imaging of bright planetary targets when used with a narrow field setup.

Why Choose This Product?

• Sony IMX432 Colour Global Shutter Sensor: 1600×1100 pixels, 9 µm pixel size, 1.1-inch format — delivers rich, natural colour in a single exposure.
• Ultra-Low Read Noise: As low as 2.4e in HCG mode for clean, low-noise colour imaging.
• High Frame Rate Mode: 109 fps at full resolution in 12-bit for lucky imaging workflows.
• Dual-Stage TEC Cooling: Up to 42°C below ambient with ±0.1°C precision temperature control.
• Anti-Dew Window Heater: Four adjustable levels of dew prevention for reliable all-weather operation.
• 512 MB DDR3 Buffer + USB 3.0 5 Gbps: Stable, loss-free data transmission for extended imaging sessions.
• Up to 1-Hour Exposures: Captures the faintest details in deep sky targets.
• Bonus Inclusion: Free Tilter included with purchase for improved flat field correction.

Recommended Uses

• One-shot colour deep sky imaging of nebulae and galaxies
• Star cluster and wide-field astrophotography
• Lucky imaging of bright planetary targets
• Colour imaging without the need for LRGB filter sets

Compatibility and Accessory Notes

• Requires an external 12V 3A DC power supply or stable 11–14V lithium battery — not included
• Compatible with ToupTek OAG-L and OAG-X off-axis guiders
• Compatible with ToupTek AFW-L motorized filter wheel for light pollution and narrowband filters
• M42 thread connection; adapter rings may be required for some telescopes
• Supported by ToupTek StellaVita smart controller
• Compatible with INDI, ASCOM, SharpCap, NINA, and APT

Important Limitations

• Requires an external power supply — cannot operate on USB power alone
• Colour Bayer sensor — not suitable for pure narrowband (Hα/SII/OIII) imaging without a duo-narrowband filter
• Not recommended for beginners without prior cooled camera experience

Frequently Asked Questions

What is the difference between the ATR432C and ATR432M?
The ATR432C is a one-shot colour (OSC) camera with a Bayer colour filter, while the ATR432M is monochrome. The colour version is simpler to use but less flexible for narrowband imaging.

Does the ATR432C work for narrowband imaging?
It can capture narrowband data with a duo-narrowband filter (e.g., Ha/OIII), but dedicated monochrome narrowband imaging requires the ATR432M.

What is included in the package?
The ATR432C includes the camera body, 12V power adapter, USB cable, and a free Tilter accessory for flat field correction.

Our Recommendation

The ToupTek ATR432C is an excellent one-shot colour cooled camera for intermediate to advanced deep sky imagers who want the simplicity of colour imaging with professional-grade thermal performance. The free Tilter inclusion adds extra value for flat field correction. If you prefer monochrome imaging with full narrowband capability, consider the ATR432M instead.
